I use Foxmarks to keep different computers' bookmarks sync'ed to each other. I have one set of bookmarks for use on home computers, and another set for use at work computers. (I also use delicious for low usage bookmarks I know I want available everywhere.)

With Foxmarks, you can sync your bookmarks to their servers, or you can sync to your own webdav server. I prefer to host my own stuff, so I sync to my own webdav server. The bookmarks are stored in JavaScript's json file format.

But, that doesn't give me the option to browse to the server and easily see the other set of bookmarks. (If I sync'ed to Foxmarks' servers, then I could see them at my.foxmarks.com if I login with my other username.)

What's a Pythonista to do? Write a script that displays the bookmarks as URLs on a webpage! Sweet! Now I host my own repository for my bookmarks, and they're available online in case I need to see the other set's bookmarks. Here's the script:
